I've got a quick question related to the DNS and telnet/ftp services. Currently I have one machine that has CNAME entries in the DNS data. i.e. www.icon.com.au (NOTE that this is not an Internet Connected) which is a CNAME for t-rex.icon.com.au using 10.0.0.1 There is also a CNAME to ftp.icon.com.au Can I prevent people telnet'ing to either of these CNAME's whilst still allowing telnet access to t-rex.icon.com.au ? Similarly, how about inhibiting ftp access to all but ftp.icon.com.au ? My guess is I'm going to have to set up some kind of IP aliasing. Finally, given that my domain name is icon.com.au is there anyway to set up finger so that it will report all users using a machine on that domain ? i.e. finger icon.com.au reports who is logged in on t-rex.icon.com.au, bob.icon.com.au, fred.icon.com.au etc... ? Thanx in advance, David Henshaw
